CPT® Code 73592

A radiologic examination, specifically CPT® Code 73592, refers to the imaging of the lower extremities in infants, which includes a minimum of two views. This procedure primarily focuses on the tibia and fibula, the two long bones located in the lower leg. The examination may also encompass the knee and ankle joints, providing a comprehensive view of the distal lower extremities. X-ray imaging employs indirect ionizing radiation to create images of the internal structures of the body. The principle behind X-ray imaging is based on the varying densities and compositions of human tissues, which allow certain X-rays to be absorbed while others pass through. This differential absorption results in a two-dimensional representation of the bones and surrounding tissues on a detector. The primary purpose of conducting X-rays of the tibia and fibula is to investigate potential causes of symptoms such as pain, limping, or swelling. Additionally, these radiographs are instrumental in diagnosing various conditions, including fractures, dislocations, deformities, degenerative diseases, osteomyelitis, arthritis, foreign bodies, and the presence of cysts or tumors. Furthermore, X-rays of the tibia and fibula are utilized to assess the alignment of lower extremity bones following treatment for fractures, ensuring that healing is progressing correctly. The standard views captured during this examination include the anteroposterior (AP) view, which is taken from front to back, and the lateral view, which is taken from the side. It is important to note that CPT® Code 73592 is specifically designated for X-ray examinations of the lower extremities in infants, typically defined as individuals aged 30 days to 24 months, and requires at least two views to be included in the study.
